Edible Uses

Edible Parts: Fruit Edible Uses: Fruit - raw or cooked. Very nice raw when it is fully ripe, preferably picked after a frost[K]. At this stage it has a mealy texture and a mild-flavoured slightly sweet fruit. The fruit can also be bletted. This involves storing the fruit in a cool dry place until it is almost but not quite going rotten. At this stage the fruit has a delicious taste, somewhat like a luscious tropical fruit. The fruit is up to 15mm across[200].

Medicinal Uses

None known

Known Hazards

The seeds probably contain hydrogen cyanide. This is the ingredient that gives almonds their characteristic flavour. Unless the seed is very bitter it should be perfectly safe in reasonable quantities. In small quantities, hydrogen cyanide has been shown to stimulate respiration and improve digestion, it is also claimed to be of benefit in the treatment of cancer. In excess, however, it can cause respiratory failure and even death.
